Magneto-Transport in Epitaxial Thin Film $Sb_{2}Te_{3}$

ORAL

Abstract

We report magneto-transport measurements in epitaxially grown thin films of $Sb_{2}Te_{3}$. $Sb_{2}Te_{3}$ is a topological insulator candidate expected to possess a single Dirac cone on its surface.\footnote{H. Zhang et al., Nat. Phys. 5, 438 (2009).} Both semiconducting and metallic samples were measured, identified by the temperature response of their resistivities. Shubnikov-deHaas (SdH) oscillations were found in measurements with fields up to 9T in metallic samples at liquid helium temperature, but have yet to be observed in semiconducting samples. Measurements will be presented along with plans for further research.
